SPECIFICATION forming part of Letters Patent No. 283,891, dated August 28, 1883. Application filed December 29. 1582. (No model.)

To a. whom. it may concern:

Be it known that we, WOLOOTT A. H LL, of New York, in the county and State of New York, and FRANK S. TRUnsDnLL, of Ansonia, in the county of New Haven and State of Connecticut, have invented a certain Improvement in Lamp-Fixtures, of which the following is a specification.

This improvement consists in the combination, in a'lamp-fixture, of a stationary part,

an extensible part, and a telescopic rod, whereby we produce a very compact fixture having an extensible part, which has a very great range of adjustment.

The improvement also consists in other fea tures, which will hereinafter be described, and then pointed out in the claims.

In the accompanying drawings, Figure l is a side view of a chandelier embodying our improvement. Fig. 2 is a similar view, showing a portion of the parts in a different position in dotted outline. Fig. 3 is a view illustrative of the manner in which certain side arms are fastened to a yoke or cross-piece. Fig. i

2 5 is a View illustrative of the manner in which a guide for an extensible part is secured to the side arms; and Fig. 5 is a sectional view illustrative of certain features in the construction of a shade-support and a crown, which is to be used on the shade.

Similar letters of reference designate corresponding parts in all the figures.

A designates two side rods or arms, which extend downwardly in parallel positions for 3 5 some distance, and then flare outwardly toward the lower ends, where they are provided with means for supporting lamps. These arms are secured at the top to a yoke or cross-piece, B, and near the lower ends they are secured together by means of a guide-piece, C. This guide-piece is provided with sockets or eyes a, which are slipped over the arms and rest upon pins I), which are inserted in the arms. Setscrews 0, extending through the sockets 4 5 and impinging against the arms, serve to maintain the arms and guide-piece in their proper relative positions. At the upper ends of the arms are square or polygonal portions d, which fit in correspondingly-shaped sockets in the yoke or cross-piece B, and above these poryoke or cross -piece together.

.tact with the guidepiece.

tions are screw-threaded nipples or terminals 6. Nuts f, fitting on these terminals above the yoke or cross-piece, secure the arms and A loop, is secured to the yoke or cross-piece, for suspending the chandelier.

D designates an extensible part or harp, which at the lower end supports a lamp and comprises two parallel portions, which extend upward through the guide-piece C. These rods extend through tubes E, preferably made of metal, which fit snugly in holes in the guide piece, and so guide the parallel portions of the extensible part or harp. At both the upper and lower ends these tubes are provided with collars or flanges h, which preclude them from passing entirely through and out of the guide-piece. WVhen the extensible part or harp is lowered, the tubes descend with it through their gravity, and when the extensi- 7o ble part or harp is raised the tubes are raised by it. The tubes rest upon spiral springs i,

which surround the parallel portions of the extensible part or harp above a shade-holder, F, which is attached thereto.

To the upper ends of the parallel portions of the extensible part or harp are attached chains G, which extend upwardly over pul= leysj, arranged in the yoke or cross-piece B, thence down around pulleys k, arranged upon a cross bar attached to a counterbalanceweight, H, and thence upwardly to the yoke or cross-bar, where their ends are fastened- The counterbalanceweight surrounds and travels along a rod, I, which extends between the yoke or cross-piece B and the guide-piece C. The parallel portions of the extensible part or harp and the tubes E may be regarded as telescopic rods. It will be readily understood that when the extensible part or harp descends the tubes E descend with it until the collars or flanges h at their upper ends come in con- The extensible part or harp then descends still farther, the tubes serving to guide it thereafter to the end 5 of its movement. By this means we obtain a great range of movement for an extensible part or harp with short rods; hence the chandelier will. be very compact when the extensible part or harp is raised, while the latter part will be capable of far more than the usual amount of extension.

Instead of chains, any suitable tackle may be used.

5 The shade-holder is made of sheet metal, and comprises a cylindrie or approximately cylindrie upper part and a flaring lower portion. The upper part has spring-tongues Z extending from it, and formed by slitting the 10 metal and bending outward the portions surrounded by the slits. Against these tongues the upper part of the shade J rests.

K is a crown, made of sheet metal and fitted outside the shade. It has affixed to its inte- 15 rior 'springtongues m, which are adapted to impinge upon the shade with a resilient pressure.

- What we claim as our invention, and desire to secureby Letters Patent, is

1. In a lamp-fixture, the combination of a stationary pai't, an extensible part comprising 7 a telescopic rod, a guide-piece'for the rod, and a chain or tackle attached to the lower section of the rod, substantially as specified.

2. In a lamp-fixture, the combination of a stationary part, an extensible part comprising a telescopic rod, a guide-piece for the rod, and a chain ortackle attached to the lower section of the rod, pulleys around which the chain or tackle is passed, and a counterbalance-weight, substantially as specified.

3. In a lamp-fixture, the combination of a stationary part, an extensible part comprising telescopic rods, a guide-piece, chains or tackle attached to the lower sections, the pulleys j 70, 3 5 and a counterbalanceweight, substantially as specified.

4. The combination. of the extensible part or harp D, the tubes E, and the springs 1', substantially as specified.

5. The combination of the side rods or arms A, the guide-piece O, with its sockets or eyes a, the pins b,1and the set-screws a, substantially as specified.

6. A shade-holder made of sheet metal, and 5 consisting of an upper approximately cylindric portion and a flaring lower portion, the upper cylindric portion being provided with spring-tongues Z, formed by slitting the said eylindric portion and bending outward the 50 portions surrounded 'by the slits, substantially as specified:
